DTIM works without the store delay stall. Still a bit of work remaining. The DTIM needs cleanup.

The cache needs a bit of clean up and the chapter needs updates.
The controller needs to be updated to remove the store delay hazard for cmo instructions.

Fixed Zicclsm bug. Misalignment and spill detection were not masked by access type. Therefore a page table walk which always aligned could have had an IEUAdrM misaligned which erroneously caused a shift in the read data.
